BACKGROUND OF THE INVENTION

1. Field of the Invention

The present disclosure relates to a portable terminal installed thereinwith a gyro sensor.

2. Discussion of the Background Art

Typically, a portable terminal is a mobile device that has one or morefunctions such as performing of voice and video call communication, datainput/output and data storage.

With such diverse functions, the portable terminal has evolved into acomprehensive multimedia device that can support various operations,such as capturing images or videos, reproducing music or video files,allowing the user to play games and receiving broadcast contents.

To realize complex instructions, some conventional devices are equippedwith a motion detection sensor so that a user may give instructions viaa motion commands. However, the conventional devices are deficient formany reasons, including requiring that users remember specific motionpatterns relative to all the instructions as operation modes. Also, theconventional devices are deficient because unintentional motions of auser may generate an erroneous operation by the portable terminal.

SUMMARY OF THE INVENTION

The present disclosure solves the aforementioned drawbacks of theconventional art by providing a portable terminal and a driving methodof the same capable of giving instructions by using a motion patterncoincident with an intuition of a user.

The present disclosure is related to a portable terminal and a drivingmethod of the same capable of giving instructions using a motion patterncapable of avoiding confusion of motion patterns.

An objective of the present disclosure is to increase the number ofinstructions applicable to a motion pattern and to prevent an erroneousoperation resultant from an unintentional motion pattern by analyzingthe motion pattern using the motion pattern and an input from anothermanipulation device.

According to one general aspect of the present disclosure, there isprovided a portable terminal including: a motion sensing unit forsensing a motion of the portable terminal; a manipulation unit forreceiving a manual manipulation of a user; and a controller forinterpreting a value inputted from the manipulation unit and a userinstruction from a motion pattern sensed by the motion sensing unit.

Thus, there is an advantage in that the portable terminal can combinethe input of the manipulation unit and the motion pattern to receivevarious cases of instructions from the user and to resultantly increasea user convenience and a user satisfaction.

According to another general aspect of the present disclosure, there isprovided a driving method using a portable terminal, including:recognizing a motion of the portable terminal to check an input of atouch screen or a designated key button; interpreting a user instructionfrom a motion pattern comprised of motion detection values of the motionsensing unit during an input of the touch screen or the designated keybutton; and executing the user instruction.

Thus, there is an advantage in that the portable terminal executing thedriving method can be applied to interpretation, as the userinstruction, of only the motion pattern derived from motion valuesgenerated from an intentional touch of the touch screen or depressing ofthe designated key button to thereby prevent an erroneous operation bythe motion sensing unit.

There is an advantageous effect in the portable terminal and the drivingmethod of the same thus described in that user conveniences can beincreased. For example, an instruction can be given using a motionpattern consistent with intuition of a user and the number of userinstructions using the motion pattern can be increased. Furthermore, anerroneous operation of a portable terminal caused by unintentionalmotion under a portable environment can be avoided.

It should be noted that two more constituentelements may be combined in a single element, or a single element may bedivided into two or more elements when in actual implementation.

Now, these constituent elements will be sequentially described indetail.

The radio communication unit 110 may include a broadcasting receptionmodule 111, a mobile communication module 112, a wireless internetmodule 113, a short-range communication module 114 and a GPS module 115.

The broadcasting reception module 111 receives broadcasting signaland/or broadcasting related information from an external broadcastingmanagement server (not shown) via a broadcasting channel. Thebroadcasting channel may include a satellite channel or a terrestrialchannel or some other type of communication channel. The broadcastingmanagement server may refer to a server that generates and transmitsbroadcasting signals and/or broadcasting associated information or aserver that receives previously generated broadcasting signals and/orbroadcasting associated information and transmits such to a terminal.The broadcasting associated information may refer to information relatedto a broadcasting channel, a broadcasting program or a broadcastingservice provider. The broadcasting signal may include, not only a TVbroadcasting signal, a radio broadcasting signal, a data broadcastingsignal, but also a broadcasting signal obtained by combining a databroadcasting signal with a TV broadcasting signal or a radiobroadcasting signal.

Meanwhile, the broadcasting associated signal may be provided via amobile communication network, and in such a case, such information maybe received by the mobile communication module 112.

The broadcasting associated information may be implemented in variousformats. For example, the broadcasting associated information mayinclude an EPG (Electronic Program Guide) of a DMB (Digital MultimediaBroadcasting) format, or an ESG (Electronic Service Guide) of a DVB-H(Digital Video Broadcasting-Handheld) format.

The broadcasting reception module 111 receives broadcasting signals byusing various digital broadcasting techniques, and particularly, thedigital broadcasting signals can be received by using digitalbroadcasting techniques, such as DMB-T (Digital MultimediaBroadcasting-Terrestrial), DMB-T (Digital MultimediaBroadcasting-Satellite), MediaFLO (Media Forward Link Only), DVB-H(Digital Video Broadcasting-Handheld) and ISDB-T (Integrated ServicesDigital Broadcasting-Terrestrial). It should be also noted that thebroadcasting reception module 111 may be configured to be suitable forany other broadcasting technique that provides broadcasting signals andinformation.

The broadcasting signals and/or broadcasting associated informationreceived via the broadcasting reception module 111 may be stored in thestorage 160.

The mobile communication module 112 transmits and receives radio signalsto and from at least one device out of a base station, an externalterminal and a server of a mobile communication network. Here, the radiosignals may include voice call signals, video (or conference)communication call signals, data in various formats based on thetransmission and reception techniques used, text/multimedia messages andother types of information.

The radio internet module 113 refers to a module that supports a radioaccess to a network such as interne, and may be installed in the mobileterminal or may be implemented as an internal or external element.

The short range communication module 114 refers to a module thatsupports short range communications. Suitable technologies forimplementing this module may include Bluetooth, RFID (Radio FrequencyIdentification), IrDA (Infrared Data Association), UWB (Ultra Wideband)and ZigBee. The GPS module 115 receives navigational information from aplurality of satellites.

Meanwhile, the A/V input unit 120 is configured to receive audio signalsor video signals and may include a camera module 121 and a microphonemodule 122. The camera module 121 function, to process image frames suchas motionless images or videos (moving images) that are obtained by animage sensor in a video call (or video conference) mode or in an imagecapture mode. The processed image frames may then be displayed on adisplay module 151.

The image frames processed by the camera module 121 may be stored in thestorage 160 or transmitted to outside via the wireless communicationunit 110. Two or more camera modules 121 may be provided according toconfiguration and aspects of the portable terminal.

The microphone module 122 receives an external sound signals from amicrophone in a calling mode, a recording mode or a voice recognitionmode and processes such into an electrical audio (voice) data. Theprocessed audio data may be converted for output into a format that canbe transmittable to a mobile communication base station via the mobilecommunication module 112 in a calling mode. The microphone module 122may include various types of noise canceling algorithms (or otherprocessing mechanisms) to cancel noise generated in the course ofreceiving the external audio signals.

The manipulation unit 130 may generate key input data based on userinputs to control the operation of the portable terminal. Themanipulation unit 130 may be formed as a key pad, a dome switch, a touchpad (e.g., employing touch recognition techniques based on pressure,capacitance, resistance and the like), a jog wheel and a jog dialswitch. Particularly, when the touch pad is combined with the displaymodule (151, described later) in a layered structural manner, such maybe called a touch screen.

The sensing unit 140 senses a current state (or configuration) of theportable terminal (i.e., an opened or closed state), a location (ororientation) of the portable terminal 100, or whether the user hastouched certain portion of the portable terminal. Based on such sensing,a sensing signal for controlling the operation of the portable terminal100 is generated.

For example, if the portable terminal is a slide-type portable terminal,the sensing unit 140 can sense whether a slide portion of the slide typeportable terminal is opened or closed with respect to a main bodyportion of the portable terminal. In addition, the sensing unit 140 canperform a sensing function to detect whether the power supply unit 190has supplied power or whether the interface unit 170 is connected withan external device.

The interface unit 170 functions to interface with various externaldevices that can be connected with the portable terminal 100. Forexample, the external devices may include a wired or wireless headset,an external charger, a wired or wireless data port, a card socket (i.e.,for coupling a memory card and a SIM/UIM card), an audio input/outputport, a video input/output port, and an earphone. The interface unit 170may be used to receive data from the external device or be provided withpower, such that the received data or power can be delivered toparticular elements of the portable terminal 100 or may be used totransmit data and other information from the portable terminal 100 tothe external device.

The output unit 150 is configured to provide various types of outputssuch as audio signal, a video signal or an alarm signal and may includea display module 151, an audio output module 152 and an alarm outputmodule 153.

The display module 151 serves to output and display informationprocessed by the portable terminal 100. For example, the display module151 may display a particular UI (User Interface) or GUI (Graphic UserInterface) related to the call operation when the portable terminal 100is in a calling mode. The display module 151 may display a capturedand/or received image, or a particular UI and/or GUI when the portableterminal 100 is in a video calling mode or an image capturing mode.

As noted above, if the display module 151 and the touch pad are formedtogether in a layered manner to constitute a touch screen, the displaymodule 151 may be used as an input device as well as an output device.The display module 151 may include at least one of a liquid crystaldisplay, a thin film transistor-liquid crystal display, an organic lightemitting diode, a flexible display and a three-dimensional (3D) display.The display module 151 may include two or more such displays accordingto particular implementation of the portable terminal 100. For example,the portable terminal 100 may be disposed with external display module(not shown) and internal display modules (not shown) at the same time.

The audio output module 152 may output audio data that has been receivedfrom the radio communication unit 110 in a call signal reception mode, acalling mode, a recording mode, a voice recognition mode or abroadcasting reception mode, or output audio data which has been storedin the storage 160. In addition, the audio output module 152 may outputan audio signal related to a function e.g., a call signal receptionsound and a message reception sound) performed by the portable terminal100. The audio output module 152 may include a speaker and a buzzer.

The alarm output module 153 may output a signal that informs aboutoccurrence of an event of the portable terminal 100. The event occurringin the portable terminal 100 may be, for example, a call signalreception requesting a telephone call, a message reception, a key signalinput and an alarm that informs a predetermined time. The alarm outputmodule 153 outputs a signal informing about occurrence of an event in adifferent format other than an audio signal or a video signal. The alarmunit 153 may output a signal, for example, in the form of vibration.When a call signal or a message is received, the alarm output module 153may output vibration in order to inform about the received call signalor message. Alternatively, when a key signal is received, the alarm unit153 may output vibrations as a feedback of the inputted key signal. Theuser can recognize the occurrence of an event via the vibrations.Additionally or alternatively, the occurrence of an event may beinformed to the user via the display module 151 and/or the audio outputmodule 152.

The storage 160 may store software programs (or codes, instructions,etc.) used to support the processing and controlling performed by thecontroller 180 and may perform a function for temporarily storinginputted or outputted data (e.g., a phone book, a message, a stillimage, or video.).

The storage 160 may include a storage medium of at least one of a flashtype memory, a hard disk type memory, a multimedia card, a card typememory (e.g., SD card, XD card, etc.), a RAM and a ROM, just to name afew. In addition, the portable terminal 100 may cooperate with a networkstorage device capable of performing the storage function of the storage160 via network access (such as via the Internet).

The controller 180 controls the general operations of the portableterminal. For example, the controller 180 performs the controlling andprocessing associated with handling a voice call, data communication, avideo call. In addition, the controller 180 may include a multimediareproduction module 181 for reproducing multimedia data. The multimediareproduction module 181 may be formed as a hardware component within thecontroller 180 or may be formed as a software component separately fromthe controller 180.

The controller 180 may identify a proximity touch or a direct touch ofthe touch screen by an object (for example, finger of a user) to changethe size or area of a screen displayed on the touch screen. To this end,the controller 180 may be formed with a scroll bar or a mini map forcontrolling the size or area of a screen displayed on the touch screen.The detailed description of the controller 180 will be further givenhereinafter.

The power supply 190 receives external power or internal power andsupplies the power required for the operation of various elements underthe control of the controller 180.

In the above description, the portable terminal according to the presentinventive concept has been explained in terms of elements from theperspective of their functions. Hereinafter, the portable terminalaccording to the present novel concept will be explained in terms of theexternal elements with reference to FIGS. 2 and 3. For simplicity, atouch screen-type portable terminal among various types of portableterminals such as a folder type, a bar type, a swing type and a slidertype will be referred to for explaining the exemplary implementations.However, it can be clearly understood that the features described hereinare not limited to the touch screen-type portable terminal, but can beapplicable to any type of portable terminal.

FIG. 2 is a front perspective view of the mobile terminal according toone exemplary implementation of the invention. The methods describedbelow may be implemented in other device configurations as well.

The portable terminal 100 includes a first body 100A and a second body100B formed to be slidably moving along at least one direction on thefirst body 100A. In other implementations, the bodies may flip orrotate, or may share a common body.

A state in which the first body 100A is disposed to overlap with thesecond body 100B may be called a closed configuration, and as shown inFIG. 2, a state in which the first body 100A is moved to expose at leasta portion of the second body 100B may be called an open configuration.

In the closed configuration, the portable terminal operates mainly in astandby mode, and the standby mode may be released according to a usermanipulation. In the open configuration, the portable terminal operatesmainly in the calling mode, and the operation state may be changed intothe standby mode upon lapse of a certain time or according to usermanipulation.

The case (a casing, a housing, a cover and the like) constituting anexternal appearance of the first body 100A consists of a first frontcase 100A-1 and a first rear case 100A-2, and various electroniccomponents are installed in a space there between. At least one or moreintermediate cases may be additionally disposed between the first frontcase 100A-1 and the first rear case 100A-2.

The cases may be formed by injection-molding of a synthetic resin or maybe made of a metallic material, such as stainless steel (STS) ortitanium (Ti). On the first body 100A {e.g., substantially on the firstfront case (100A-1)}, the display module 151, the first audio outputmodule 152-1, the first camera module 121-1 or a first manipulation unit130-1 may be disposed.

The display module 151 includes an LCD (Liquid Crystal Display), an OLED(Organic Light Emitting Diode), or the like that visually displaysinformation.

A touch pad may be overlaid (overlapped, superimposed, covered) on thedisplay module 151 in a layered manner to allow the display module 151to operate as a touch screen, whereby the user may input information orcommands (instructions) by touching the display module 151.

The first audio output module 152-1 may be implemented as a receiver ora speaker to output various types of sounds.

The first camera module 121-1 may be suitably implemented for capturingstill images, moving images, videos, or other visual information.

The manipulation unit 130-1 receives user commands (instructions) forcontrolling network contents reproduction and travel guide operations.

Like the first body 100A, the case constituting the external appearanceof the second body 100B consists of a second front case 100B-1 and asecond rear case 100B-2.

A second manipulation unit 130-2 may be disposed on the second body100B, specifically, on a front face portion of the second front case100B-1.

A third manipulation unit 130-2, a microphone module 122, and aninterface unit 170 may be disposed on at least one of the second frontcase 100B-1 or the second rear case 100B-2.

The first to third manipulation units 130-1, 130-2, 130-3 may becollectively referred to as the manipulation unit 130, and any means canbe employed as the first to third manipulation 130-1, 130-2, 130-3 solong as it can be operated in a tactile mariner.

For example, the manipulation unit 130 may be implemented by using oneor more dome switches or touch pads that can receive a user command orinformation according to press or touch operation by the user, or may beimplemented by using a mechanical manipulation means, such as arotatable element (e.g., a wheel, dial, jog button, thumbwheel, etc.) ora linear movement element (e.g., a joystick, lever, knob, etc.).

In terms of functions thereof, the first manipulation unit 130-1 maycomprise one or more function keys used for inputting a command such asstart, end or scroll, and the second user input unit 130-2 may compriseone or more keypads used for inputting numbers, characters, and symbols.

The third manipulation unit 130-3 may be operated as a so-called hot keyfor activating a special function of the portable terminal.

The microphone module 122 may be suitably implemented for receiving avoice of the user or other sounds.

The interface unit 170 may be used as a passage (path or link) thatallows data to be exchanged with an external device through a wired orwireless medium. For example, the interface unit 170 may be at least oneof a connection port used for connection of an ear jack, earphones, andthe like, a communication port that supports short-range communications(e.g., an IrDA port, a Bluetooth™ port, a wireless LAN port, etc.), anda power supply port used for supplying power to the portable terminal.

The interface unit 170 may include a card socket for receiving oraccommodating a card-like medium, such as a SIM (SubscriberIdentification Module) card, a UIM (User Identity Module) card and amemory card for storing information.

The power supply unit 190 may be mounted at the side (or edge) portionof the second rear case 100B-2 for use in supplying power to theportable terminal 100. The power supply unit 190 may be a rechargeablebattery, which can be releasably and attachably formed with the portableterminal.

FIG. 3 is a rear perspective view of the portable terminal according toone exemplary implementation.

Referring to FIG. 3, a second camera module 121-2 may be additionallymounted on the rear surface of the second rear case 100B-2 of the secondbody 100B. The second camera module 121-2 may have an image capturedirection which is substantially opposite to that of the first cameramodule 121-1 (See FIG. 1), and may support a different number of pixelswhen compared to the first camera module 121-1.

For example, preferably, the first camera module 121-1 is used for lowresolution (i.e., supporting a relatively small number of pixels) toquickly capture an image (or video) of the user's face for immediatetransmission to another party during video conferencing or the like,while the second camera module 121-2 is used for high resolution (i.e.,supporting a relatively large number of pixels) in order to capture moredetailed (higher quality) images or video which typically do not need tobe transmitted immediately.

A flash 121-3 and a mirror 121-4 may be adjacently disposed at thesecond camera module 121-2. When an image of a subject is captured bythe second camera module 121-2, the flash 150 illuminates the subject.The mirror 121-4 allows the user to see himself or herself when he orshe wants to capture his or her own image (i.e. perform self-imagecapturing) by using the second camera module 121-2.

A second audio output module 152-2 may be additionally disposed on thesecond rear case 100B-2, and may implement a stereophonic function inconjunction with the first audio output module 152-1 (See FIG. 2), andmay be also used in a speaker phone mode for call communication.

A broadcasting signal reception antenna 111-1 may be disposed at oneside of the second rear case 100B-2, in addition to an antenna used forcall communication. The antenna 111-1 may be installed such that it canbe extended from the second body 100B.

One part of a slide module 100C that slidably connects the first body100A with the second body 1008 may be disposed on the first rear case100A-2 of the first body 100A. The other part of the slide module 100Cmay be disposed on the second front case 100B-1 of the second body 100B,which may not be exposed to the outside as shown in FIG. 3.

In the above description, the second camera module 121-2 and the likeare disposed on the second body 100B, but such exemplary configurationis not meant to be limiting.

For example, one or more of the constituent elements 111-1, 121-2,121-3, 152-2 which are disposed on the second rear case 100B-2 may bemounted on the first body 100A, mainly, on the first rear case 100A-2.In this case, there is an advantage in that those elements disposed onthe first rear case 100A-2 can be protectively covered by the secondbody 100B in the closed configuration. In addition, even if a secondcamera module 121-2 is not separately mounted, the first camera module121-1 may be configured to rotate to thereby enable an image capturingup to an image capturing direction of the second camera module 121-2.

FIG. 4 is a schematic view illustrating a structure of a touch screenrelated to the present disclosure.

Referring to FIG. 4, the display module 151 may be overlaid (overlapped,superimposed, covered) on the touch pad 400 in a layered manner to allowoperating as a touch screen.

The touch pad 400 illustrated in FIG. 4 is comprised of a squaredconduction film 411 made of transparent conductive material such as ITO(Indium Tin Oxide) and metal electrodes 412-1 to 412-4 each formed atedge of each conductive film 411. The conductive film 411 may be formedthereon with a protective film 420.

The touch pad 400, a position detection device of capacitive sensingtype, is formed with electric field lines between transmission sidemetal electrodes (T: 412-1, 412-4) and reception side metal electrodes(R: 412-2, 412-3) by an AC (alternating current) voltage applied to thetransmission side metal electrodes (T: 412-1, 412-4). The formedelectric field lines are extended to the outside of the touch pad 400via the protective film 420.

As a result, when an object (for example, digits of a user) comes nearto the touch pad 400 or directly touches the touch pad 400, the electricfield lines are partially interrupted to generate a change on the phaseand size of the current flowing to the reception side metal electrodes(R: 412-2, 412-3). This is because human body has a static capacity ofseveral pFs relative to the ground to distort the electric field linesformed on the touch pad 400 when a user brings a finger near to ortouches the touch pad 400.

Processes (not shown) formed inside the portable terminal 100 may usethe current change of the reception side metal electrodes (R: 412-2,412-3) in response to the touch operation of the object to detect adistance neared by the object and a position where the touch hasoccurred.

In addition, the object may include not only the finger of the user, butalso all the objects capable of identifying the touch input by theportable terminal 100, by distorting the electric field lines formed onthe touch pad 400.

FIG. 5 is a schematic view illustrating a principle for detecting aproximity distance of an object using the touch screen of FIG. 4.

Referring to FIG. 5, application of AC voltage 430 to the transmissionside metal electrode 412-1 out of metal electrodes 412-1 to 412-4 formedon the transparent conductive film 411 makes it possible to formelectric field lines (i.e., electric lines of force. 501 to 503 betweenthe transmission side metal electrode 412-1 and the reception side metalelectrode 412-2. The electric field lines 501 to 503 may be extensivelyformed to a vertical upward direction (i.e., z direction) of the touchscreen 500.

The amount of electric field lines 501 to 503 interrupted, by a finger510 may be changed base on the proximity distance to the touch screen500 neared by the finger 510 of the user. In other words, as the hand510 nears the touch screen 500, the finger 510 may increase theinfluence applied to the electric field lines 501 to 503.

As noted above, the influence applied to the electric field lines 501 to503 by the finger 510 changes the current applied to current detectionunits 440-1, 440-2 connected to the metal electrodes 412-1, 412-2, wherethe current detection units 440-1, 440-2 detect the changed current andprovide the change to an ADC (Analog-to-Digital Converter. 450). The ADC450 converts the current amount inputted in the form of analog signal toa digital value and provides the digital value to a touch timemeasurement unit 460.

The touch time measurement unit 460 measures a time stayed by the finger510 within a touch identification (recognition) effective distance(i.e., ‘d1’ of FIG. 5) capable of identifying proximity of the finger510 by the touch screen 500 from the information relative to the changedcurrent amount provided by the ADC 450. In doing so, the touch timemeasurement unit 460 may recognize that the proximity touch or directtouch operation is being performed if the finger 510 stays beyond apredetermined time (i.e., 1 second) within the proximity touchidentification effective distance (i.e., ‘d1’ of FIG. 5). Meanwhile, ifthe finger 510 stays shorter than a predetermined time (i.e., 1 second)within the proximity touch identification effective distance (i.e., ‘d1’of FIG. 5), the touch time measurement unit 460 may determine that theproximity touch or direct touch operation is not being performed.

If it is determined that there is a touch input in response to theproximity touch or direct touch operation relative to the touch screen500, the touch time measurement unit 460 may provide to a distancedetection unit 470 information on touch input generation information andcurrent change amount.

The distance detection unit 460 may calculate a distance between thefinger 510 and the touch screen 500, i.e., a distance separated from thetouch screen 500 by the finger 510 toward the vertical upward direction(i.e., z direction) from the information on the provided current changeamount.

To be more specific, if the finger 510 is positioned at a locationnearer than d1 from the vertical direction of the touch pad 400 (i.e., zdirection) but further than d2 (i.e., 20 mm, a location between d1 andd2), the distance detection unit 460 may determine that the finger 510has entered within the touch identification effective distance fromwhich to detect whether the touch screen 500 starts to be touched by anexternal object, and may provide a function corresponding to theproximity touch operation. The proximity touch is defined by a state ofan object (i.e., finger of a user) being positioned within the touchidentification effective distance of the touch screen 500 for inputtinga user command. The proximity touch of the object not directly touchingthe touch screen 500 may be distinguished from the direct touchoperation that directly touches the touch screen 500 by the object.

Furthermore, if the finger 510 is positioned on a location nearer thand2 (i.e., 20 mm) from the vertical direction of the touch pad 400 (i.e.,z direction) but further than d3 (i.e., 10 mm, a location between d2 andd3), the distance detection unit 460 may determine that the finger 510has fairly approached the touch screen 500. If the finger 510 ispositioned on a location shorter than d3 (i.e., 10 mm) (i.e., positionedwithin d3) from the vertical direction of the touch pad 400 (i.e., zdirection) (i.e., positioned within d3) or the finger 510 has directlytouched the surface of the touch screen 500, the distance detection unit460 may determine that the finger 510 has directly touched the touchscreen 500 within the error scope.

Although the touch operation of the finger 510 has been described inthree steps according to the distance between the finger 510 and thetouch screen 500, the description of the touch operation may beclassified to four steps for further accuracy.

Successively, a position detection unit 480 may calculate frominformation on the changed current amount a position on the touch screen500 indicated by the finger 510, i.e., a horizontal coordinate of x andy direction on the touch screen 500. The y direction is a verticaldirection relative to x and z directions illustrated in FIG. 5.

The measured vertical distance discrete between the finger 510 and thetouch screen 500 and the horizontal coordinate of the finger 510 on thetouch pad 400 may be transmitted to the controller 180. In so doing, thecontroller 180 may check the user command according to the verticaldistance and the horizontal coordinate to perform a control operation inresponse to the user command and concurrently provide a predeterminedgraphic user interface (GUI).

FIG. 6 is a schematic view illustrating a position detection principleof an object using the touch screen of FIG. 4.

Referring to FIG. 6, when an AC voltage is applied from the AC voltagesource to the transmission side metal electrodes 412-1, 412-4 of thetouch panel 400, electric field lines (not shown) are formed betweentransmission side metal electrodes 412-1, 412-4 and the reception sidemetal electrode 412-2, 412-3.

In addition, if the finger 510 comes near onto the touch panel 400 ordirectly touches the touch panel 400, current changes are generated tothe metal electrodes 412-1 to 412-4. The current detection units 440-1to 440-4 measure the current changes, and as described above, theposition detection unit 470 detects the horizontal coordinate (i.e., x-ycoordinate) located on the touch panel 400 by the finger 510 via thecurrent changes and provides the coordinate to the controller 180. Thecontroller 180 now may recognize the horizontal coordinate on the touchscreen 500 touched by the finger 510 to perform the user commandcorresponding to the touch operation and provide the predeterminedgraphic user interface (GUI) onto the display module 151.

Although FIGS. 5 and 6 has described the touch time measurement unit460, the distance detection unit 460 and the position detection unit 480separately according to their functions, these units 460, 470, 480 maybe formed inside the controller 180.

Although the touch screen 500 equipped with the touch panel 400according to capacitance detection type has been exemplified in FIGS. 4,5 and 6 to explain the principle of determining the proximity touch anddirect touch of object relative to the touch screen 500, there is nolimit of arrangement shapes of the metal electrodes 412-1 to 412-4 ofthe touch panel 400 or the kinds of touch panel 400 as long as thefunction is provided for detecting the position indicated by the objectand the distance between the object and the touch screen 500.

For example, the touch panel 400 may be embodied to detect a proximityposition between the object and the touch panel 400 using aphotoelectric sensor that uses laser diodes and light emitting diodes, ahigh frequency oscillation proximity sensor and electromagneticproximity sensor. The touch panel may also be embodied by combining thecapacitance detection type and the resistive sensing type by formingmetal electrodes on an upper plate or a lower plate for detectingvoltage changes according to a position pressed by the object.

Now, functions of constituent elements for embodying the idea of thepresent disclosure out of constituent elements of FIG. 1 and embodimentmeasures will be emphatically described.

The sensing unit 140 of the portable terminal according to the presentexemplary implementation may be equipped with a motion detector, such asa gyro sensor or the like for detecting motion of the portable terminal.

The manipulation unit 130 may be equipped with a key pad disposed with aplurality of key buttons, and may be formed with a touch screen fordetecting a coordinate value of a point designated by a user. In someexemplary implementations, other pointing-receiving devices replacingthe touch screen may be used, but the touch screen may be the mostappropriate pointing-receiving device in the present exemplaryimplementation in view of the fact that a user applies a shakingoperation to the portable terminal while the touch screen is beingtouched.

The controller 180 may interpret a value received from the manipulationunit 130 and a motion pattern detected by the motion detector as a userinstruction. Preferably, the controller 180 determines a motion patternfrom detection values of the motion detector during a period (e.g.,during a period of a particular key button being depressed, or a periodof a touch screen being depressed) in which a value received from themanipulation unit 130 keeps a predetermined value.

The motion detector may be embodied by a three-axis acceleration sensor,which may be selected from various products on the market inconsideration of an appropriate size suitable for installation in aportable terminal and performances.

The known method for calculating a displacement in pattern (hereinafterreferred to as displacement pattern) using the three-axis accelerationsensor is disclosed in various ways, such that detailed explanationthereto will be omitted herein. But a principle of calculating thedisplacement pattern using the three-axis acceleration sensor will beexplained in the following simple manner. That is, in consideration ofthe tact that an integral value of an acceleration becomes a speed, andan integral value of the speed becomes a distance that is moved, adisplacement pattern of an object installed with the three-axisacceleration sensor can be obtained from accumulation of theacceleration values relative to orthogonal three axes, if a stoppedpoint is known.

In some exemplary implementations, the motion detector is a two-axisacceleration sensor which is less expensive than the three-axisacceleration sensor, or a gyro sensor of other methods. The motiondetector may further include a one-axis, two-axis or three-axis rotationdetection sensor for sensing the rotating motion. The motion detectormay calculate three-axis acceleration values for knowing a gravitydirection, or may further include a gravity detection sensor.

In some exemplary implementations, the motion detector may outputdetection values in various types. For example, the motion detector mayoutput a displacement pattern of a portable terminal, or may simplyoutput three-axis acceleration values. The type of output may bedetermined by complexity of displacement pattern to be applied forinputting an instruction. Embodiment of using the displacement patternis preferred, when various kinds of instructions are involved anddisplacement patterns are complex, and embodiment of three-axisacceleration output values is preferred, when the number of instructionsis limited and displacement patterns are simple.

In some exemplary implementations, the controller 180 may refer todirectivity of the motion pattern recognized by the motion detector inorder to determine directivity of vibration pattern. This is to allow auser to determine directivity of vibration pattern in response to aholding state of a portable terminal, whereby the user can have the samefeeling relative to the vibration pattern regardless of the directivityof the potable terminal held by the user. To this end, the vibrationgenerator is preferred to be disposed with two or more vibrationelements each having a different vibration direction (preferablyorthogonal direction).

When the vibration generator is disposed with two or ore vibrationelements each having a different vibration direction, the vibrationdirection of motion pattern applied by a user and vibration directionapplied by the vibration generator may be correlated.

For example, when a user holds a portable terminal in a lengthwisedirection, and an instruction to a particular application is selectivelygiven in a lengthwise vibration direction or a cross-wise vibrationdirection of the portable terminal, it is assumed that a user hasselected the lengthwise vibration direction. At this time, anaffirmative response to the user instruction may be embodied bygeneration of a length-wise vibration direction applied by the user, anda negative response to the user instruction may be embodied bygeneration of a cross-wise vibration direction which is the oppositedirection. To this end, it is preferable that the storage 160 of theportable terminal be disposed with an area for recording a vibrationdirection of motion pattern applied by the user.

Preferably, the controller 180 may apply an approximate value indetermining motion patterns because each of the motion patterns (albeitidentically recognized by the user) may differ a bit according to user'spsychological state. For example, a pattern within a predeterminedapproximate value from a recorded pattern may be considered as therecorded pattern.

The controller 180 may use one or more parameters selected from a groupconsisting of displacement, speed, acceleration speed, direction,rotation direction and the parameters are obtained from detection valuesof the motion detector, One or more of these parameters are used forinterpreting motion patterns. The motion patterns recognized by thecontroller 180 may be divided into reciprocation motion, circularmotion, hit or push as instantaneous acceleration, rotation and complexpattern motion (e.g., 8-shaped motion and zigzag motion).

A predetermined area allocated to the storage 160 of the portableterminal of FIG. 1 may be stored with data (e.g., DB) for supporting thedriving method of the portable terminal.

For example, the storage 160 may be equipped with a motionpattern-instruction DB in which one field is allocated for an identifierof a particular key of depressed state or touch screen (partial orentire area), another field is allocated for motion pattern and stillanother field is allocated for interpreted instruction. The DB serves toassist the controller 180 in interpreting the user instruction frommotion pattern during an input value designated by the manipulation unit130.

FIG. 7 is a flowchart illustrating a driving method of a portableterminal according to an exemplary implementation of the presentdisclosure.

The driving method using a portable terminal illustrated in FIG. 7comprises: recognizing a motion of the portable terminal to check aninput of a touch screen or a designated key button (S120); interpretinga user instruction from a motion pattern comprised of motion detectionvalues of the motion sensing unit while there is an input of the touchscreen or the designated key button (S140); and executing the userinstruction (S160).

The step of S120 may comprise: recognizing motion detection values fromthe motion detector of the portable terminal (S122); and monitoring, bythe controller of the portable terminal, whether the touch screen or aparticularly designated key has been depressed (S124). The steps of S122and S124 may be performed simultaneously, or one of the two steps (S122and S124) may be performed before the other step, or the other step maybe performed after the first step.

The constituent element of manipulation unit 130 for monitoring whetherthe touch screen or the particularly designated key has been depressedin step S124 may be a key (hereinafter referred to as side key) button(B1) positioned at a side of the portable terminal as illustrated inFIG. 9 a, a particular key (hereinafter referred to as gyro key) button(B2) allocated for function setup of the gyro sensor as illustrated inFIG. 9 b, a specific partial area (IR1) on the touch screen asillustrated in FIG. 9 c, a call/termination key button (K1) asillustrated in FIG. 9 d, or may be a software key button (IK1) formed atthe touch screen as illustrated in FIG. 9 e.

As a result of step S120, motion detection values may be obtained thathave been accumulated in the period when the touch screen of theportable terminal or the particularly designated key button beingdepressed. The step of S140 may comprise: checking the motion pattern(S142); and interpreting an instruction from the motion pattern (S144).

The controller of the portable terminal in step S142 may detect motionpatterns from the accumulated motion detection values. For example,three-axis acceleration values obtained at a predetermined interval maybe integrated to obtain three-axis speed values, which is furtherintegrated to obtain three-axis displacement values. Changes of thethree-axis displacement values would allow directly determining theshapes of the motion patterns.

In some exemplary implementations, the displacement pattern of aportable terminal may be applied as the motion pattern, or thethree-axis acceleration values may be simply applied as the motionpattern. A complex exemplary implementation may include a motion patternadded by directions and whether rotation has been effected.

When kinds of instructions to be applied are in large numbers, anembodiment of complex displacement pattern is preferred, and when thekinds of instructions are in small numbers, an embodiment of using asimple value such as two/three-axis acceleration output values ispreferred. A simple push motion may be represented by a two-axisacceleration sensing value, and a motion tilting to a predetermineddirection may be given by three-axis acceleration value.

FIGS. 10 a to 10 d are conceptual drawings illustrating concrete motionshapes of a portable terminal applicable as motion patterns according tothe idea of the present disclosure. As illustrated in FIGS. 10 a to 10d, kinds of motion patterns may include a tilting (FIG. 10 a), a90-degree rotation (FIG. 10 b), a shaking (FIG. 10 c), a complex motionfollowed by a push (FIG. 10 d).

Meanwhile, parameters discerning each motion pattern may includestrength of shaking as illustrated in FIG. 11 a, degree and/or directionof tilting as illustrated in FIG. 11 b (i.e., each motion of P1˜P8 shownin FIG. 11 c may be discernable each other), size of motion as shown inFIG. 11 c (i.e., each width of motion in P11˜P13 of FIG. 11 c may bediscernable each other), and concrete shapes of motions.

In step S144 of FIG. 7, in order to determine a user instructionrepresented by motion pattern detected from step S144, a motionpattern-instruction DB may be used. The DB is comprised of one field foran identifier of a particular key or touch screen (partial or entirearea) is depressed, another field for a motion pattern, and stillanother field for an instruction.

In step S160, the controller 180 may perform in a form of executing anapplication or a task. Performance of a particular task within anoperational system or an application program of a central processingunit in computer equipment is well known, such that the detailedexplanation thereto will be omitted. The driving method of a portableterminal in FIG. 7 may be performed during various menu executions, andapplied to various operation modes or applications.

A user in the present exemplary implementation may control an operationof the portable terminal by applying two kinds of inputs. The two kindsof inputs include a first input via a manual manipulation unit operatedby a motion of a user using a finger, and a second input via a motiondetector (gyro sensor) detecting a motion pattern applied to theportable terminal.

Methods for applying the two kinds of inputs may include a methodsimultaneously applying the first input and the second input, a methodsequentially applying the first input and the second input within arelatively short waiting time, and a method partially overlapping a timeof the first input being applied with a time of the second input beingapplied.

Among the three methods, the method of simultaneously applying the firstinput and the second input is preferable in terms of user convenience(e.g., when a user applies a shaking operation with a particular keybutton being depressed) and in order to prevent an erroneous orunintended operation caused by detecting a motion pattern by theportable terminal. However, it should be noted that the three methodsare all useable for embodying the idea of the present disclosure, andare within the scope of the present disclosure.

FIG. 8 is a flowchart of a process of a portable terminal detecting anotion pattern that is applied during depression of a designated keybutton by a user. The portable terminal checks the motion pattern basedon motion values detected for a period from a time of the designated keybutton being depressed to a time of the designated key button beingreleased. The motion values may be periodically obtained using the gyrosensor.

If the above-mentioned process is applied to the flowchart of FIG. 7,the step of S120 of FIG. 7 may include checking the depression of thedesignated key button (S112), starting to detect the motion using thegyro sensor when the depression of the designated key button isgenerated (S113), and checking the release of the designated key buttonin the course of motion detection (S114) and terminating the motiondetection if the designated key button is released (S116). Meanwhile, aprocess (S115) of repeating the motion detection during depression ofthe designated key button may be repeated in a form of limitless loop.The method ends when the motion pattern is actually detected (S117).

When the motion detection is finished, the motion pattern isdiscriminated using the motion values obtained during depression of thedesignated key button (S142). The step of S142 in FIG. 8 corresponds tothe step of S142 of FIG. 7. The discrimination of motion patterns fromthe periodic acceleration sensing values is known to the skilled in theart such that detailed explanation thereto will be omitted.

In some implementations, the depression of the designated key button maybe replaced by touch of touch screen or touch of a particular area(e.g., soft key) on the touch screen.

Now, various cases of driving method in FIG. 7 will be described withreference to drawings illustrating a display screen of the portableterminal.

FIG. 12 illustrates a case of enlarging a touched file when a shakingmotion is applied during touch by a user of a desired image of theportable terminal equipped with a touch screen. The desired image is ona file list viewed in form of thumbnail list.

An enlargement ratio of a touched file image may be determined byshaking times (frequency) during depression of a desired image (IR2) asshown in the drawing. Furthermore, it may be also possible to enter intoa touched file view mode if applied with the shaking motion during touchof the desired image.

Alternatively, as illustrated in FIG. 13, it may be possible tocontinuously enlarge an interested image whenever the shaking motion isapplied after a particular image (IR2) is selected as the interestedimage by the depressing motion on the touch screen, and it may be alsopossible to finally change an entire area of the interested image into adisplay mode as the shaking motion continues.

The thumbnailed image file list is easy to touch and is adequate torealize the above-mentioned ways. However, an image file list arrangedin lengthwise format or a message list may also be applied to thepresent implementation.

FIG. 14 illustrates an instance where a single image is selected anddisplayed when a portable terminal is shaken in a mode of a particularkey button being depressed by a user and image files being displayed ina thumbnail or a similar format.

The illustrated thumbnail screen is applied with a design allocated to adifferent size of area relative to each image in order to increaseaesthetic feeling of a user.

Referring to FIG. 14, a normal thumbnail list is displayed on thescreen. And a first combination of a particular key button and aparticular motion pattern {gyro key (B2)+shaking on the drawing} isapplied, an interested image (I, an image to be displayed on an entirescreen by a selective operation to be followed) is enlarged larger thanother images of thumbnail format, and a second combination of anotherparticular key button and a particular motion pattern {gyro key(B2)+tilting on the drawing} is applied under this circumstance, theenlarged interested image (IM) is displayed on the entire screen.

Meanwhile, when the normal thumbnail list is displayed on the screen,and a third combination of a particular key button and a particularmotion pattern {side key (B1)+shaking on the drawing} is applied, theinterested image (I) is displayed on the entire screen.

The first, second and third combination may be discriminated byallocation of a different key button that is depressed, and/or byapplication of a different motion pattern.

In some exemplary implementations, when the first combination of aparticular key button and a particular motion pattern {gyro key(B2)+shaking on the drawing} is applied, any one image on the thumbnailmay be randomly set up as a desired image.

In some exemplary implementations, an operation of touching one imageamong a plurality of thumbnailed images displayed on the touch screenmay replace the operation of depressing the particular key button. Inthis case, the touched image is preferably set up as the desired image.

FIG. 15 illustrates an instance where a message of pre-designatedcontent is transmitted to a sender of the message when a user depressesa particular key button to shake a portable terminal and to check thereceived message.

Referring to FIG. 15, when there is no time by the user who has checkedthe message to prepare a reply message to a relevant message, and whenthe user shakes the portable terminal during depression of the gyro keybutton (B2), the user can send a reply message of a pre-designatedcommonly used words or phases.

The illustrated exemplary implementation has a practical advantagebecause an excuse can be easily obtained from a message sender withoutgenerating a noise when a user requests a silence.

Alternatively, when a user shakes the portable terminal duringdepression of the particular key button and a call comes in under anawkward environment, the on-going call may be terminated and apre-determined message may be displayed to the user and/or may betransmitted to the caller who has just dialed up.

FIG. 16 a illustrates an scenario where a message including commonlyused words is transmitted to a telephone number registered in hot numberwhen a user shakes a portable terminal in a mode of a message key button(MK) being depressed in the conventional reception waiting mode.

Referring to FIG. 16 a, when a user depresses the message key button(MK) to shake the portable terminal, the portable terminal may select adesired phone number among a plurality of stored phone numbers and senda message in response to a motion pattern. As illustrated, strength ofthe shaking or the shaking times (frequency) may be applied asparameters of motion patterns that determine the hot number. As shown inFIG. 16 b, the message may be one of a commonly-used word list, or amessage specially registered for this method. In another embodiment, afirst shake or series of shakes may result in a first predeterminedword/phrase presented to the user to confirm before sending. If thefirst predetermined word/phrase is not desired, the user can revealanother predetermined word/phrase by again shaking/controlling thedevice.

Alternatively, when the portable terminal is in the conventionalreception waiting mode, and a user shakes the portable terminal duringdepression of a message key button, it may be possible to enter into amode for preparing a message to be sent to the telephone numberregistered in hot number.

FIG. 17 illustrates an instance where a call connection is tried to atelephone number registered in hot number when a user shakes a portableterminal during depression of a call key button in the conventionalreception waiting mode of the portable terminal.

Referring to FIG. 17, when a user shakes the portable terminal duringdepression of the call key button, the portable terminal may select adesired number among a plurality of hot numbers and try the callconnection in response to a motion pattern. The strength of the shakingor the shaking times (frequency) may be used as parameters of motionpatterns that determine the hot number. In another embodiment, a firstshake or series of shakes may result in a first hot number presented tothe user to confirm before sending. If the first hot number is notdesired, the user can reveal another hot number by againshaking/controlling the device.

FIG. 18 illustrates an instance where a call connection is tried to atelephone number registered in a numeral hot number, when a portableterminal is shaken in the numerical shape during depression by a user ofa particular key (gyro key on the drawing) in the conventional receptionwaiting mode.

Referring to FIG. 18, when the user constructs a ‘2’ shape by shakingthe portable terminal in a depressed state of the gyro key button (B2),the portable terminal recognizes the motion pattern as ‘2’ and tries tomake a call connection to a hot number registered as ‘2’, and when theuser constructs a ‘2’ shape by shaking the portable terminal in adepressed state of the message key button (MK), the portable terminalrecognizes the motion pattern as ‘2’ and transmits a message includingcommonly-used words to the hot number registered as ‘2’.

In some exemplary implementation, when the portable terminal is shakenduring depression of the number key button, a call connection (or amessage transmission) may be attempted to a telephone number registeredas a number hot number of the key button.

FIG. 19 illustrates an instance where an video call view mode ischanged, when a user depresses a particular key button or a touch screento apply a shaking motion in the video call mode of a portable terminal.

Referring to FIG. 19, when the user shakes the portable terminal duringdepression of any one key button, an opponent image enlarged view modemay be changed to my image enlarged view mode.

In some exemplary implementation, a video call mode of a portableterminal equipped with a touch screen may be changed to a touched imageenlarged view mode if the portable terminal is shaken during a touch ofa particular image, or the touched image may be transmitted instead.

FIG. 20 illustrates an instance where a designated operation isperformed, when a user depresses a particular key button and shakes aportable terminal in a DMB (Digital Multimedia Broadcasting) receptionmode.

Referring to FIG. 20, if a user who has watched the DMB shakes theportable terminal during depression of a call key button (MC), theportable terminal that has outputted the DMB is changed to a preferencechannel pre-designated by the user.

As illustrated in FIG. 20, if a user who has watched the DMB shakes theportable terminal during depression of a side key button (B1), theportable terminal that has outputted the DMB displays informationrelative to the currently-viewed channel.

As illustrated in FIG. 20, if a user who has watched the DMB shakes theportable terminal during depression of a gyro key button (B2), theportable terminal that has outputted the DMB sets up thecurrently-viewed channel as a preference channel of the user.

FIG. 21 illustrates an instance where a displayed image is enlarged orreduced, when a user applies a shaking motion during depression of aparticular key button in a mode of a particular image file of theportable terminal equipped with a touch screen being displayed.

Referring to FIG. 21, a ratio of a touched file image to be enlarged wasdetermined by the shaking times (frequency) in a state of an enlargementkey button (IK3) formed by an imaginary button at an upper side of thetouch screen being depressed, and a ratio of a touched file image to bereduced was determined by the shaking times (frequency) in a state of areduction key button (IK4) formed by an imaginary button at a lower sideof the touch screen being depressed. Furthermore, the shaking motion maybe applied to a portable terminal formed at a side thereof with anenlargement key and a reduction key relative to images. It may be alsopossible to notify a user the completion of enlargement or reduction ofan image via vibration, and to output a vibration while the enlargementor reduction is being progressed.

When an instruction of further reduction is given during display of asingle image file on an entire screen, it may be possible to display apart of a thumbnail list including the image file as shown in the firstscreen of FIG. 22.

Referring to FIG. 22, when a user applies a tilting motion of theportable terminal upwards (or downwards) of the screen during display ofa part of the thumbnail list relative to the image file, a thumbnail offurther up position (or further down position) may be displayed, andwhen a horizontally-tilted motion (left or right) is performed, a left(or right) thumbnail may be displayed. An entire image of the thumbnaillist may have a brighter resolution than that of the display of theportable terminal. Even in this case, the user may be notified of theprogress of movement of the thumbnail image or completion of themovement of the thumbnail image via vibration or effect sound. Thus, auser may scroll a plurality of images with a predetermined motion.Alternatively, a user may scroll a zoomed single image with apredetermined image.

In addition, when a user applies a tilting motion of the portableterminal upwards (or downwards) of the screen during display of a partof text relative to the image file, text of further up position (orfurther down position) may be displayed, and when a horizontally-tiltedmotion (left or right) is performed, left (or right) text may bedisplayed. An entire image of the text may have a brighter resolutionthan that of the display of the portable terminal. Even in this case,the user may be notified of the progress of movement of the thumbnailimage or completion of the movement of the thumbnail image via vibrationor effect sound. Thus, a user may scroll text with a predeterminedmotion.

FIG. 23 illustrates a circumstance where an image is enlarged anddisplayed about a touched area in a mode of a particular image file of aportable terminal mounted with a touch screen being displayed, if a userapplies a shaking motion during touch of a desired area (IR3) of thedisplayed image.

Although not shown in the drawing, when another vibration patterndistinguishable from vibration pattern for enlargement is applied duringtouch by a user of a desired area on the image, it may be possible todisplay the image in reduced format about the touched area. Furthermore,the completion of enlargement or reduction of the image may be notifiedto the user via vibration or effect sound.

FIG. 24 illustrates an instance where a font of a displayed text isenlarged or reduced, when a user applies a shaking motion duringdepression of a particular key button in a mode of a particular text ofa portable terminal formed with a touch screen being displayed.

Referring to FIG. 24, a ratio of enlarging a font of the text wasdetermined according to the shaking times (frequency) during depressionof an enlargement key button (IK5) located at a lower area of the touchscreen of the portable terminal. Furthermore, it is possible todetermine a ratio of reducing the font according to the shaking motionduring depression of a reduction key button (IK6) positioned at a lowerarea of the touch screen of the portable terminal. The determination ofratio of enlargement or reduction of a font may be also applied to aportable terminal having an enlargement key and a reduction key at aside thereof. Furthermore, the user may be notified of completion ofenlargement or reduction of the font via vibration. The progress ofenlargement or reduction of the font may be also notified to the uservia vibration.

FIG. 25 a illustrates an instance where volume of bell sound is set upby the shaking times (frequency), when a user applies a shaking motionduring touch of a bell sound volume icon area (IR5) on a touch screen ina mode of a bell sound setup menu of a portable terminal equipped withthe touch screen.

Furthermore, FIG. 25 b illustrates an instance where volume of soundeffect is set up by the shaking times (frequency) when a button isdepressed, when user applies a shaking motion during touch of a buttonvolume icon area (IR6) on a touch screen in a mode of executing a buttonvolume setup menu of a portable terminal disposed with the touch screen.

In both instances of FIGS. 25 a and 25 b, a user may be notified ofcompletion of volume setup via vibration (or effect sound). Furthermore,when a predetermined delay time lapses and after volume of sound isdesignated by the shaking motion, the designated volume of sound may beautomatically set up.

FIG. 26 a illustrates an instance where a video is enlarged and/or anaspect ratio is changed in response to the shaking times (frequency),when a user applies a shaking motion while touching a video reproductionarea of a touch screen in a video reproduction mode of a portableterminal disposed with the touch screen.

FIG. 26 b illustrates an instance where volume is adjusted at a ratio inresponse to the shaking times (frequency), when a user applies a shakingmotion during depression of a gyro key button (B2) located at a side ofa portable terminal in a video reproduction mode of the portableterminal disposed with a touch screen. In both instances of FIGS. 26 aand 26 b, a user may be notified of completion of volume setup viavibration (or effect sound).

Alternatively, a user may fast forward or fast reverse through a videowith a predetermined motion of the device.

Furthermore, an electronic dictionary application may be loaded tosearch for a particular word, when a user applies a shaking motionduring touch of the particular word included in a displayed text, in amode of the text being displayed on a touch screen of a portableterminal.

In the present exemplary implementation, it is preferable that a smartphone having an excellent multitasking operating system be applied, asit is easier to apply the multitasking operating system.
